I've just changed my router, but the new one has been setup with the
same IP address (192.168.1.254).

I've also got 6 PIs on my network.  Of those, 2 seem OK, but the other
four have decided that their default gateway is now going to be
192.168.1.1.

I've used
route delete default gw 192.168.1.1 eth0
route add default gw 192.168.1.254 eth0

to reset the default gateway, but in each case, overnight the default
has reset itself back to 192.168.1.1  None of the PIs have been
rebooted.  I'm not convinced that this is a coincidence, but my WIN7 PC
also reset the default gateway mid evening (whilst I was using it),
again to 192.168.1.1.

Any suggestions on how I can persuade my PIs to stick to the proper GW ?

Thanks

Adrian
